snd-hda-intel issues

[Lintula]

Hello,

Using ALSA modules shipped with Linux 2.6.20, I find that with a HP
dc7600 workstation I need to load snd-hda-intel with model=basic or
model=hp or there is no sound. Alsamixer indicates Chip: Realtek ALC260.

00:1b.0 0403: 8086:27d8 (rev 01)
        Subsystem: 103c:3010
        Flags: bus master, fast devsel, latency 0, IRQ 18
        Memory at e04c0000 (64-bit, non-prefetchable) [size=16K]
        Capabilities: [50] Power Management version 2
        Capabilities: [60] Message Signalled Interrupts: 64bit+
Queue=0/0 Enable-
        Capabilities: [70] Express Unknown type IRQ 0

Same with a Lenovo M55 8811, except I seem to need model=laptop.
alsamixer indicates Chip: Analog Devices AD1986A.

Try this patch and report back if it works.

You can get alsa-driver-1.0.14rc3.tar.bz2 from
ftp://ftp.alsa-project.org/pub/testing/alsa-driver-1.0.14rc3.tar.bz2

If this patch works, then here's my summary in advance:

Summary:  Add support for Lenovo M55 Laptop
This patch adds support for the Lenovo M55 Laptop to the HDA drivers.
